System Check Tachometer Question

[npd4432]

Just bought a pontoon with a 1997 60HP Johnson, has VRO and System Check gauge, the boat does not have a tachometer. I would like to install a tachometer. The controls dont have the 3 wire plug under the key that I am used to. The system check gauge the boat currently has is the 2" gauge with the four warning lights, no tachometer. This gauge has the 8 pin connector on the back. My question is if I purchase a system check tachometer that has what looks like the same 8 pin connector as my current gauge, will I be able to plug in the tach and have it work without any other wiring or modifications??

Yes, the Systems Check tach has the same 8 pin connector. Look carefully at the wires in that 8 wire bundle, and you will see the familiar purple, black and grey are all present. Grey is your tach wire.

Just so you now, the dashboard harness for my '98 Johnny also has the three wires (Purple, Black, Grey) on ring terminals for a conventional Tach. Since the System Check Tach is about the same $$ as a regular one, I recomend it.
